P.S. If the child understand rounding up and rounding down, as the previous post indicated, then the number being rounded can't change; i.e., 543 rounded to the tens place is 540 (the 4 stays since the next number is 3 but it would move to 550 is we were rounding 549). Said another way, the 4 can stay or it can be one larger but not two or three larger or two or three less. The 5 in 543 can move ONLY to the 6 if we round up or it stays the same if we throw away the 43). It CAN'T change more than 1 and only then can it move one up, not two or three up and it can't move down.
